This is proof that you should never give up fighting for something or someone you love!

More than a year after losing in court the right to seek custody of his child, Jason Patric has now WON a recent MAJOR victory in his paternity case!

A victory for Jason, though, means a loss for his ex Danielle Schreiber, who had previously claimed that she used his sperm artificially — but never had any intention of raising the son Gus with Jason. She even says Jason was fully aware of it.

His kid is so cute - we're sure anyone would fight for the right to see him.

Lost Boys' Jason Patric is entrenched in a custody battle after he lost all parental rights of his son Gus.

But the actor hasn't taken his losses and given up. Instead, as he mentioned to Katie Couric - he's now not only fighting for the right to see his own son, but is also backing a new law in California that would give sperm donors more rights.

Mr. Patric claims he's had his son "stolen from him" and he hopes a new law will make sure that never happens to any sperm donating fathers ever again!

Jason Patric and his on-and-off girlfriend, Danielle Schreiber are tied up in a very odd situation. Back in 2009, the couple broke up and Patric apparently had no dough to give Danielle, so instead, he gave her his SPERM so she can have a child!
